The present invention relates to improved brackets or fixtures such as are referred to in the trade as staging brackets, the same being adapted for use in maintaining ladders in per- A pendicular positions for the construction of temporary scaffolding usable by painters, carpenters, plasterers and the like.

Although the invention is exemplified through the illustration of a completeV set-up scaffold, it will be observed, as implied in the preceding statement, that the novelty is directed to the particular construction arrangement and` mounting of the brackets employed to maintain the ladders in rigid perpendicular position.

Stated in generic terms, the` novelty is predicated upon a metal bracket somewhat in the nature of a yoke, the same being characterized by diverging attaching arms and an associated portion constructed to embrace the ladder to quick accessible means being associated with the last-named portion` to facilitate assembling the ladder in the associated brackets.

As indicated in the preceding paragraph, the invention is carried into force and effect through the instrumentality of companion selectively usable brackets accordingto the type of work to be performed, and while the lbrackets have common characteristics, certain ofthem are provided with appreciably different features such as render them especially appropriate for the particular job in hand.

Other features and advantages will become more readily apparent from the following description and drawings.

In the accompanying drawings, whereiny like numerals are employed to designate corresponding elements throughout the views:

Figure 1 is an elevational view ofthe complete staging or scaffolding in readiness for use illustrating a group of four ladder-holding brackets constructed in4 accordance with the principlesof the, present invention.

Figure 2 is a top plan View of the assemblage seen in Figure 1.

Figure 3 is an end elevation, that is, a View observing Figure l in a direction from left to right. Figure 4 is a top plan View of a modified type 55 der retention means incorporated in the bracket securely hold it in a reliable supporting. position,`

or form of bracket usable under predetermined seen in Figure 4, the View looking at Figure 4 in a direction from left to right.

Figure 'Z is an. enlarged detail View of the bracket illustrated in Figure 5 observing it from its front or outer end, showing how it is detachably mounted on the Wall or other structure.

By way of introduction to the detailed description, and by reference to Figure 5 in comparison With Figures 1 to 3, it will be observed that the bracket seen, in Figure 5 possesses the same fundamental characteristics as those shown as the main bracket in Figures l to 3. It is simply a smaller bracket so as to position the ladders 8 closer to the wall or other support 9, such as is required for plastering. ThereV are also common characteristics in the modification seen in Figure 4, so, for sake of convenience, each species or variety of bracket will be separately described, thus avoiding possible confusion. i i

Reference is made, in view of the foregoing, to the bracket shown in Figures 1 to 3. Here the bracket is denoted by the numeral l0. It is of general Y-shaped form and may be unitarily identified as a yoke. It includesa U-shaped portion Il to embrace the ladder so as to hold the ladder securely to maintain. the plank l2 securely in place. This 'U-shaped part completely embraces the ladder with one rail located in the bight portion I3; and the other rail disposed adjacent the point of divergence of the attaching arms I4. At the point underA observation is a bracket I5l on the main bracket serving as a pivotal mounting for the U-shapedlatch or clevis I6. The ends ofthe arms of the clevis project beyond the adjacent` portion of the U-shaped member l.| and are formed with eyes to accommodate a linch pin I1. The numerals IB designate anchoring cleats or plates screwed or otherwise fastened to the foundation or support, and the outer ends of the diverging arms are hingedly connected thereto-as at the points I9.

The short-type bracket illustrated in Figure 5 and shown to further advantage in Figure '7 is differentiated by the numeral 20. As before indicated, this is employed where it is desired to position the ladders close to the wall. Like the bracket already described, this one includes a U-shaped portion 2l to embrace the ladder 8 and diverging arms 22 for attachment purposes. In this instance the arms terminate in laterally bent ears or lugs 23 which are in turn provided with keyhole slots 24 to be detachably hung over the headed fasteners such as nails 25. Here the clevis 26, instead of being pivoted, is detachable and slidable, and its arms straddle the arms of the U-shaped part 2| to carry the retention or linch pin 21.

Coming now to the remaining form of the invention seen in Figure 4, here the bracket is differentiated by the numeral 28. Again, in this arrangement, We have diverging attaching arms 29 hingedly connecte-d as at 30 to anchoring cleats or plates 3|', suitably fastened to the wall. The converging ends of the arms 29 are here riveted together as at 32 with one end formed with what may be called a short extension of general L- shaped form as at 33, and this terminates in a lateral hook or detent 34, designed to accommodate a keeper notch 35 (see Figure 6) in the free end portion of the latch member 36. The latch member is hingedly connected as at 3l to the outer end of a suitably shaped and lengthened extension 38 forming a part of one of the arms 29. The part 38 coacting with the latch 36 forms a loop similar to the U-shaped members Il and 2| already described. It will be observed that the hinged end of the latch is bifurcated and one furcation is bent to form a hinge knuckle as at 39, while the other furcation forms a closing tongue 4U (see Figure 4). Assuming that the latch is open, lby placing the ladder in such a position as to bring it in pressure contact against the finger Mi, it will be observed that this finger will serve to automatically swing the latch to closed position for engagement purposes. Thus, the nger 40 is in effect an automatic closing element for the latch which is ladder operated.

Making reference again in generic terms to the several embodiments of the invention thus described, it will be seen that each bracket includes a structure which may be said to be of general Y-shaped form. The fork or diverging arms serve in each instance for attachment purposes. The stem portion is of looped form including the latch or clevis so that it completely embraces the ladder. These factors are mentioned to provide the desired foundation for the generic claims hereinafter presented. To certain brackets (Figures 1, 2, 3, 5, and 7) the ladders are placed in perpendicular or erect position first with the clevises open and then the brackets are slipped or saddled over the ladders, after which the brackets are secured to the wall. In the arrangement seen in Figure 4, it is possible to fasten the bracket on the wall iirst with the latch open and to simply press the ladder against the latch to swing the latch closed to securely maintain the ladder in place.

It is thought that the description taken in connection With the drawings will enable a clear understanding of the invention to be had. 'Iherefore, a more lengthy description is thought unnecessary.

While the preferred embodiment of the invention has been shown and described, it is to be understood that minor changes coming within the field of invention claimed may be resorted to if desired.
